Brazil's block on X comes into effect after judge's order.

This is a most excellent place for technology news and articles.
Just one note, services the size of Twitter typically use cloud infrastructure so if you block that indiscriminately you risk blocking a lot of unrelated stuff.
Their load balancers are at least bound to have dedicated addresses, maybe IP range was a bit overzealous.
In any case it's not going to be an issue of blocking port 80 on one IP and finding out that it serves five hundred semi-unrelated domains. Unrelated short of all using the same wordpress or whatnot hoster, that is.
That's the thing, that's common practice. It's basically a given nowadays for shared web hosting to use one IP for a few dozen websites, or for a service to leverage a load/geo-balancer with 20 IPs into a CDN serving static assets for thousands of domains.
